Runtime Column Propagation

Use RCP whn you dont want to specifiy da Metadata. If you turn RCP on, ALL the colums will be propagated to da output

Assume you hav a job like DB -> TF -> SF and you need to display all the columns in the database....One choice is to type in all columns in the metadata tab and do the same in TF .....If u want this torture, please go ahead :) ... or jst turn RCP on...this case, u dont hav to provide the metadata.

However remember that if your job has a SORT or RDUP stage somewhr, u need to manually propagate that one column or esle u wont be able to access it.
